Diamond-like carbon (DLC) coatings were deposited on Ti alloy (Ti-13Nb-13Zr) substrates using the plasma immersion process. The plasma immersion process, unlike the conventional techniques, allows the deposition of DLC on three-dimensional workpieces with high adhesion. We quantitatively evaluated the adhesion of fibroblasts on DLCcoated and uncoated Ti alloy at 2 h. Comparisons between sample ...
PVD diamond-like-carbon (DLC) coatings are finding increasing industrial acceptance in automotive, aerospace and medical applications due to their reduced friction and low wear coefficient. Very recently, High Power Impulse Magnetron Sputter (HIPIMS) sources have been shown to produce fluxes with very high metal ion fractions similar to those produced by arc evaporation sources, without showing...
Diamond-like carbon (DLC) is considered as a versatile coating material that finds a variety of mechanical and biomedical applications, including endoprosthesis and dental implants [1]. It provides mechanical robustness and cell-compatibility at the same time. Therefore, DLC has been extensively researched for achieving high hardness, low friction, high wear resistance to make it more sustainab...
Diamond-like carbon (DLC) coatings are widely used in industries that require high durability and wear resistance, low friction. The unique characteristics of DLC allow for the possibility creating adsorption sites lubricant additives through doping process. In this study, combined use europium-doped diamond-like (Eu-DLC), gadolinium-doped (Gd-DLC), pure an ionic liquid (IL) additive, namely, t...
Acidithiobacillus ferrooxidans type strain DLC-5, isolated from Wudalianchi in Heihe of Heilongjiang Province, China. Here, we present the draft genome of strain DLC-5 which contains 4,232,149 bp in 2745 contigs with 57.628% GC content and includes 32,719 protein-coding genes and 64 tRNA-encoding genes. The genome sequence can be accessed at DDBJ/EMBL/GenBank under the accession no. JNNH0000000...
A discotic liquid crystal (DLC), HBC-C12, coating was successfully applied to improve the corrosion resistance of an iron surface. The iron surface with the DLC-coating exhibited improved corrosion resistance in various environments, including exposure to air and solutions with different pH values. To the best of our knowledge, studies regarding corrosion protection using DLCs have never been r...
BACKGROUND Antibacterial coatings of medical devices have been introduced as a promising approach to reduce the risk of infection. In this context, diamond-like carbon coated polyethylene (DLC-PE) can be enriched with bactericidal ions and gain antimicrobial potency. So far, influence of different deposition methods and ions on antimicrobial effects of DLC-PE is unclear. METHODS We quantitati...
Background This economic evaluation quantifies the cost-effectiveness of early laparoscopic cholecystectomy (ELC) versus delayed laparoscopic cholecystectomy (DLC) in the management of acute cholecystitis. The two interventions were assessed in terms of outcome measures, including utilities, to derive quality-adjusted life years (QALYs) as a unit of effectiveness. This study hypothesizes that E...
Segmentation of paraxial mesoderm in vertebrates is regulated by a genetic oscillator that manifests as a series of wavelike or cyclic gene expression domains in the embryo. In zebrafish, this oscillator involves members of the Delta/Notch intercellular signaling pathway, and its down-stream targets, the Her family of transcriptional repressors. Loss of function of any one of the genes of this ...
An electroactive passivation for high-voltage diodes with bevel termination has been investigated based on diamondlike carbon (DLC) films. Variations of the DLC properties, i.e., conductivity and geometry, have by experiments numerical simulations to purpose gaining an insight their influence diode leakage current breakdown voltage. The role played DLC/Si interface characterizing metal–DLC–Si d...
